We present a versatile microfluidic Raman system with a tunable freeform-segmented reflector for conventional Raman and Surface-Enhanced Raman Scattering (SERS) analysis. We perform systematic simulations and implemented a proof-of-concept demonstration setup. With our microfluidic Raman system, we discriminate 100µM urea and KNO3, and 10µM Rhodamine B solutions.

Several novel approaches for the design of GaAs-based VCSELs and VCSEL arrays for data com and automotive applications at 850–1310 nm are reported. They are based on optimising the photon lifetime and oxidizing the apertures from previously etched holes. Using QDs as active material at longer wavelengths is suggested.

We investigated power enhancement of THz wave with arrayed antennas and parallel-connection UTC-PDs. Combining these two configurations in 8-arrayed UTC-PDs, we demonstrated that the peak power of the THz wave at 300 GHz was enhanced by 60 times compared with a single UTC-PD.

Optical devices formed by organic materials have been applied to holographic memory to realize fast and numerous reconfiguration contexts in information processing. Therefore, we construct the optical system to demonstrate wavelength multiplex recording using lasers with different wavelengths to improve diffraction characteristics of holographic gratings formed in liquid crystal composites.

We demonstrate vertically-stacked photovoltaic/bypass diode module to generate a lifted output voltage (4.24V) with linear shadow response in electrical power (around 0.2 mW per PV cell) in a compact manner (4.84 mm2). The proposed device configuration allows further integration of sensor circuits and super-capacitors to realize a compact self-powered system.
